All my measurements where in ft, I was really thrown off when the people told me the target was 3 METERS away. so remember, 1 meter (almost) equals 1 yard.

I'm officially in Trajectory this year. I'm excited!
Anyways, if we use a screwdriver with a string attached as the pin to hold the arm in place and our launch mechanism is simply to yank it out, would that be a violation of the rules, specifically the part that says "the triggering device must not pose a danger to anyone due to flying parts or excessive movement outside the launch area"?
Edit: I just noticed the best possible score for Trajectory this year is -200. That's sort of weird.

Read the rules. It tells you what you can and can't use.
If you read the rules, you'll see that they say you can use any non-metallic elastic solid.

You can start by reading the first post in the thread, look through those links then read the rest of the thread. If this thread was 50 pages I would understand not looking through it, but when it's 4 pages you should read the entire thread before posting something like "How do I make a catapult" or "What design should I use."
